Description
Technical field
The present invention relates to recording unit and recording method, and can be applicable to such as the video recording apparatus of interface being arranged with computing machine.According to the present invention, by and the pattern and the pattern of record of the interface of computing machine and record data such as flow datas such as video datas between, can conversion temporarily store data and with the buffer sizes of data recording to the record buffer of recording medium, in view of the above, even constitute and to carry out the data input and output to computing machine and improve compatibility with computing machine, also can reduce the capacity of memory buffer.
Background technology
In the past, integrated being configured to of gamma camera of video cassette recorder: by to the video data that object image-forming produced wanted at the enterprising line item of recording medium, described recording medium comprises tape.In recent years, proposed to use various recording units to replace tape such as disc recording mediums such as hard disks.
The various interface that is widely used in such as messaging devices such as computing machines is provided.Can consider to contain record and reclaim equiment, constitute simply by utilizing this existing interface such as disc recording mediums such as hard disks.Utilize those interfaces can constitute record and reclaim equiment simply,, utilize scope so allow record and reclaim equiment to enlarge it so that can carry out the input and output of data to personal computer.
Yet, be necessary for the record of this configuration and reclaim equiment and data be sent to record and reclaim equiment provides jumbo memory buffer.
Fig. 1 in the accompanying drawing is that expression is used for the block scheme of video data stream in the recording unit of recording video data.Based on video data,, be necessary to transmit video data with the speed of about 10 (Mbps) in order to ensure enough image qualities by MPEG (motion picture expert group) compression.Shown in the structure, scrambler 2 is with the speed output of about 10 (Mbps) video data as flow data.
Such as disc recording mediums such as hard disc apparatus with about 2 times data transfer rate from scrambler 2 output video data recording video data off and on thereon, because recording medium 3 need comprise the tupe that rotates standby mode, searching modes and retry pattern.Therefore, when from scrambler 2 during with the speed output video data of about 10 (Mbps), as flow data, video data is sent to recording medium 3 with the data transfer rate of maximum 20 (Mbps).
Video data is sent to personal computer (PC) 4 by the interface (I/F) 5 according to IEEE (international Institute of Electrical and Electronics Engineers) 1394 or USB (USB (universal serial bus)) etc. and exports from personal computer (PC) 4, and by comprising the interface of ATAPI (AT additional packet interface), the record of service recorder medium 3 and reclaim equiment carry out input and output to video data, to carry out and no problem exchanges data according to the interface of IEEE 1394.Thereby prevent that in order to reduce that the personal computer 4 that has connected interface 5 is transmitted data frequency back and forth the treatment effeciency of personal computer 4 is low, the record of service recorder medium 3 and reclaim equiment require the memory buffer of about 4 (M bytes).Described ATAPI has the data transfer rate of 100 (Mbps).
When from the video data recording of scrambler 2 output during at recording medium 3, in the system buffer device 6 that is connected to scrambler 2 and ATAPI interface and be connected in the driving impact damper 7 of recording medium 3, transmitting data volume can change as shown in Figure 2.In Fig. 2, from the data of scrambler 2 output, from the data of system buffer device 6 outputs and from the data of recording medium 3 outputs respectively with symbol D1, D2, D3 representative.In Fig. 2, the perfect condition of rotation standby mode and other moulds is ignored by system in record and reclaim equiment.
When the opening entry video data (REC begins), from scrambler 2 with 10 (Mbps) output video data D1 ((A) Fig. 2) as the compression of flow data.System buffer device 6 and driving impact damper 7 accumulated video data D1 also export the video data D1 ((B)~(E) among Fig. 2) that is accumulated discontinuously.Particularly, when video data in system buffer device 6 is accumulate to institute quantitatively the time (at moment t1 place), be accumulated in data in the system buffer device 6 and be sent to 100 (Mbps) and drive impact damper 7 (t1~moment t2 during) constantly, it begins data recording to recording medium 3 with 20 (Mbps).
When system buffer device 6 and the data volume that drives accumulation in the impact damper 7 are decreased to institute quantitatively the time, system buffer device 6 and drive the transmission that impact damper 7 stops data.This handles sequence and repeats subsequently.
If drive the capacity that impact damper 7 has 4 (M bytes), then since drive impact damper 7 will be with the video data of the data transfer rate input of 100 (Mbps), data transfer rate with 20 (Mbps) exports recording medium 3 to, the input of event video data drives the data transfer rate of impact damper 7 greater than the data transfer rate of video data from 7 outputs of driving impact damper, thereby video data little by little is accumulated in the driving impact damper 7.Particularly, in 0.5 (second) of moment t1, video data is accumulate to the data volume of 4 (M bytes) in driving impact damper 7, thereby has not been free storage territory in driving impact damper 7.This moment, system buffer device 6 is necessary to stop the output of video data.
At the opening entry video data after system buffer device 6 stops the video data input driven impact damper 7, system buffer device 6 dominant records the video data of 5 (M bytes).Therefore, if the hypothesis total system is operated with desirable state, then system buffer device 6 requires to guarantee the memory capacity of at least 5 (M bytes).
Fig. 3 of accompanying drawing represents the state that makes a mistake when video data is recorded to recording medium 3, and the video data that is stored in the system buffer device 6 will send once more.Because system buffer device 6 must be stored the video data that sends once more, so system buffer device 6 needs big capacity.In the example depicted in fig. 3, constantly the video data that sends of t1~t2 is at moment t3 or retry afterwards, and system buffer device 6 is necessary to guarantee the memory capacity of 9 (M bytes).
Therefore, if use jumbo driving impact damper, thereby can be to computing machine input and output data, to improve the compatibility with computing machine, be used for that flow data is supplied with the memory buffer (system storage) that drives impact damper and require to have memory capacity greater than several times of the memory capacity that drives impact damper.

And personal computer between exchanges data the time (Fig. 4), in recording unit 11, temporarily be accumulated in the driving impact damper 17A from the data of interface 24 inputs, and be recorded on the hard disk 18, and temporarily be accumulated in from the playback of data of hard disk 18 and drive among the impact damper 17A, and export personal computer to.Driver piece 17 makes a determination, and is the high capacity of 4 (M bytes) to set the buffer sizes that drives impact damper 17A.
After the instruction of having exported record or playback of data, personal computer is sent to recording unit 11 with two-forty with data based on the response from driver piece 17, after this can carry out other processing.Otherwise up to the playback of data of having accumulated capacity in recording unit 11, personal computer can be carried out other processing, and can so obtain playback of data from recording unit 11 between other processing.So recording unit 11 can transmit and receive data to computing machine, can prevent computer access continually, and can have the high-affinity with computing machine.
In order to write down the flow data of representing image pickup result, the buffer sizes that drives impact damper 17A is set at 0.5 (M byte), so lower the capacity of system buffer device 16A necessity.
Shown in Figure 9 as with Fig. 2 contrast, when the buffer sizes that drives impact damper 17A is set at 0.5 (M byte) and the data volume of system buffer device 16A when increasing to 5 (M bytes), in order flow data to be recorded on the hard disk 18 by driving impact damper 17A at moment t1, t3, t5, begin after system buffer device 16A transmission data at moment t1 place immediately, owing to have empty storage territory driving impact damper 17A place, so with the data transfer rate of 100 (Mbps) flow data is sent to driving impact damper 17A from system buffer device 16A.
The flow data that driving impact damper 17A will so transmit is recorded on the hard disk 18.Owing to flow data is that data transfer rate with 20 (Mbps) writes down, so drive the deficiency that impact damper 17A runs into empty storage territory immediately.Drive block 17 indication mechanism impact dampers 16 are waited for by the ATAPI interface and are transmitted data.When in driving impact damper 17A, having the spatial domain, drive impact damper 17A licensing system piece 16 transport stream data when being recorded in along with data on the hard disk 18.
So in system buffer device 16A, the data transfer rate of driver piece 17 is limited in 20 (Mbps), it is to the speed on hard disk 18 with data recording.Drive the flow data of impact damper 17A storage 0.5 (Mbps).
Shown in Figure 10 as with Fig. 3 contrast, for example, if for flow data, sent from driver piece 17 and to have sent requirement again in moment t1 place transmission, then system block 16 can send the so much flow data amount by 17 storages of driver piece again, and from then on can correspondingly reduce and send the necessary storage of flow data territory again.That is, contrast as seen with Fig. 3, system buffer device 16A has the memory capacity of 5.5 (M bytes).
According to present embodiment, therefore, system buffer device 16A has the memory capacity of minimizing, and from then on can make the whole mechanism simplifying of equipment.
